+# [[CSS RWD Intro]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Responsive web design is about creating web pages that look good on all devices, using HTML and CSS to automatically resize, hide, shrink, or enlarge a website so it adapts to desktops, tablets, and mobile phones. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Responsive web design** — about creating web pages that look good on all devices. [S1]
+- **HTML + CSS** — RWD uses HTML and CSS to automatically resize, hide, shrink, or enlarge a website, to make it look good on all devices. [S1]
+- **Device coverage** — targets desktops, tablets, and mobile phones. [S1]
+- **Essential elements** — the viewport `<meta>` tag, flexible layout (grid and flex), and media queries. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Adapt, do not duplicate** — one set of HTML/CSS resizes and rearranges itself per device, rather than maintaining separate sites. [S1]
+- **Three-pillar foundation** — the viewport meta tag, a flexible layout (grid/flex), and media queries together enable responsiveness. [S1]
+
+## 📖 세부 내용 (Details)
+Responsive web design is about creating web pages that look good on all devices. Responsive design involves using HTML and CSS to automatically resize, hide, shrink, or enlarge a website, to make it look good on all devices. [S1]
+
+The page identifies three essential RWD elements: the viewport `<meta>` tag, a flexible layout (grid and flex), and media queries. It also references three device categories — desktops, tablets, and mobile phones — with accompanying device illustrations. [S1]
+
